In my views I think w should do research for both present and future generations. If you do it for present generations you might know some pitfalls and scientists can explore more in that for future generations. Anyways it also depends on the type of research conducted. For example some might take a year to get the results and some medical might take 4-5 years. According to me research is an on going evergreen thing so whether it is used immediately or i future it would be beneficial for all. So according to me both are important and should exist side by side.
